seat opens into a bore'8 leading'to an inlet 9" on the back face offlang 4. Outwardfr'omthis seat the bore-of chamber 6 is tapped toprovide a steep pitchsquarethread l'iwhic'h accepts the closing screwl0on valve stem l2. A packing nut I4 is then threaded into the-end ofthe-body to enclose the stem and compress: packing ring it. On the endof stem l2 a single wing handle l'lis splined and heldby ase't screwz Aclosing spring I8 surrounds shaft II with one end anchored to flange Aand the-other'setinto" handle ll.

The inner portion of spout chamberli is drilled spout l9, and the outer;portion threadedto receive gland nut 20. A portion of the wall ofchamber 6 is broken away to communicate with each of three portholes-'22, drilled through" the body part 3 parallel withitsaxisbuteccentrical lypositioned therefrom and opening into the: valvechamber 5. The combined crosssection'al' area of these three holes isless than that of either the inlet 9' or spout I 9, and togetherthey'form a constricted transfer passageway from the'valve chamber 5 to thespout: chamber 6-.

The spout has a threadedv axial portion 2.4" which retains it inposition, and is their bent at: right anglesto provide a delivery'bib'extend; ing fromportion 25 at an angle; of 9orelative to theaxialportion 2,6; This construction e'n-; ables the spout to be. swungout outward" for: delivery as, shown by the, solid lines in Fig: .2; orrotated to anout-oi-the-way position as indie} cated by'the. dotted:outlineiifi'. s s

Thevalve form shown in Figure 9 isof similar construction exceptthatxthe outerrtipr35xof spout [9. is, bent downward tov beparallel. to:the inner threadedportionqfl. v

' The advantages of" construction are obvious: By providing-a valve:bodywitha. cylindrical-body 3 tangentiallyjoined; to, an attaching:flangei'l';

the valve is very compact and is advantageous where space is to beconserved.

In use, the flange 4 is attached to a wall 21, which may be a sink back,or other vertical member, and the inlet tube 39 attached to a watersupply pipe. The valve thread I, having a steep pitch, will open thevalve on a quarter or half" turn. The handle is, therefore, positionedon the. stem so that it is vertical when the valve plug l3" is seated,as shown in Figure 3. When not .in; use, the spout I9 is kept intheraised position, .l5

as shown in Figure 2, or swung to one side as in dicated by numeral 38,Figure 9. When it-is to be used it is turned to the outward extendedposition-.- Outward motion ofthe handle l1 then opens the valve againstthe tension of spring I8.

A retum-motion closes it and this is accelerated by the urge of-thisspring. v i

When the valve is opened water flows from the inlet into-the valve seatchamber, 5, as indicated by the arrows Figure 4. It then reverses itsdi-.

motion and flows through holes 22 at an increased velocity due to theconstricted area of these holes, and thence at a slower velocity, intoand through chamber 6 and, lastly, out through spout l9.

Now, when valve plug 28 is closed on seat I to 30 eil'ect ashut oil,water flowing through holes 22 at the greater velocity will continue toflowon through chamber 5 and out of spout IQ for an instant-due to itsmomentum of flow. This breaks the water columns flowing through theseholes forming a partial vacuum in each. An instant after the vacuum hasformed the out flow of water from the spout tip is stopped and the endportion of water in the spout drawn back into the spout by atmosphericpressure. The quicker the 40 closing action the greater is the vacuumaction. Spring l8 assists in this. This action prevents any drip fromthe spout since the water is drawn back into it and away from its mouth.The size and shape of the'spout is such that the water in it does nottend to run out after the closing of the valve, and after it has beendrawn away from the tip of the spout. Thus, since there is no water leftat the tip of the spout to drip off, and since the remaining water doesnot tend to run out, due

cross sectional area slightly less than that of the opening throughspout I9 and spout chamber 6. Together, these openings, downstream ofthe valve, from outlet passageways having a constricted area less thanthat of the inlet 9, bore 8,

and valve chamber'5, on the upstream side of the valve closure. Waterentering from supply tube 39 under a constant head flows through thewhole valve system at a constant rate of flow. Since passageways 22 areconstricted-that is, have a smaller aggregate cross section than thepassageways upstream of the valve-and since spout 19 has an interiorpassageway only slightly larger, the rate of flow downstream from thevalve will be faster than that upstream thereof. The .flowl will attain,its greatest speed through passage! ways 22. The flow through thesepassageways, as well as through spout It, builds up kinetic energyaccording to the well known formula M V K where K=kinetic energy, M=mass and V=velocity. The result is that, despite surface friction andretarding due to change of direction, the velocity of flow is greaterdownstream of the valve than upstream of the valve and is greater thanwould be the case if the downstream passageways were the same size asthe upstream passageways, or, were not constricted. The constriction-ofpassageways 22 (as well as spout [9) therefore, is responsible for thetranslation of kineticenergy from the potential energy of the headpressure, and for the increase of velocity in thezdownstreamxflow: Underthese conditio s, when the valve is quickly closed the kinetic; en ergyin the downstream flow'carries the column ofj'water in passageways 22and in spout 19 outward until itris dissipated by friction and thepressure of the atmosphere. This accounts for the formation of "apartial vacuum in the upper ends of passageways 22 for an instant afterthe valve is quickly closed., The kinetic energy and momentum of flowcarry a portion of the water column on out of the end of the spout. Thenext instant, after this energy has been expended, atmospheric pressureforces the column of water remaining in these passageways back from theendof spout I9 and upinto them until thevacuum disappears.

Theoretically, disregarding friction, the smaller the downstreampassageways, the greater the above described effect. Practically,constriction is limited as the point is reached where friction ofisetsthe gain in kinetic energy due to increased velocity. for the purposeshere desired.

Another result of the constriction of passageways. 22 is that, since thevelocity of flow through them is greater than it would be if they werenot constricted, the water column travels further through them (alongtheir length) during the first instant, above mentioned, after the valveis closed. Thus a greater length of water column is run out of the endof spout I9, and therefore there is a greater length of pull back intothe spout the next instant, than there would be, if there was noconstriction on the downstream side of thevalve.

While .I have described the preferred forms of my device,'it.'is obviousthat many modifications can be made, but that the resultantdevicewouldstill remain within the spirit and intendments of my invention, andtherefore, wish to be limited only by the following claims.
